As of 2005, there are more than 10 ethanolamine producers in China with a total capacity of over 56,000 tons/year. The annual production capacity of major manufacturers is: 25,000 tons of Fushun North Chemical Company, 10,000 tons of Fushun Huafeng Chemical Factory, 5,000 tons of Jihua Chemical Company, 10,000 tons of Yixing Yinyan Chemical Company, and 3,000 tons of Jiamusi Beijia Chemical Factory. There are 3,000 tons of the Third Petrochemical Chemical Plant, 2,000 tons of Qingjiang Petrochemical Company, 1,000 tons of Wenzhou Qingming Chemical Plant, and 1,000 tons of Tianjin Organic Chemical Plant.
Compared with the international advanced level, domestic ethanolamine production still has many deficiencies: Many small and medium-sized enterprises are in stop production or semi-discontinued state due to small scale of production, poor product quality, and high production cost. The operating rate is less than 50%; most of ethanolamines in China The device is a certain distance away from the raw material ethylene oxide origin, and the outsourcing of ethylene oxide has the risk of interruption of supply, and ethylene oxide is a dangerous chemical. As the transportation cost is high, the production cost will rise accordingly; domestic ethanolamine production There are still deficiencies in technology such as material consumption, energy consumption, and product separation. Some indicators of the product are still lacking, and the color of the product is poor. When used in high-end cosmetics, it is difficult to meet user requirements.
Ethanolamine is an important organic raw material and can synthesize many important fine chemical products such as ethyleneamine, polyvinylpyrrolidone (PVP), and pesticide glyphosate. The domestic demand for ethyleneamines depends on imports. The annual import volume is about 12,000 tons. At present, China has already built a set of 10,000-ton scale equipment, which needs to consume about 7,000 tons of ethanolamine per year; PVP is an important fine chemical and widely used. Applied to medicine, food and beverage, daily chemical, coating, textile printing and dyeing and other fields, the current domestic demand mainly depends on imports. It is predicted that the annual average growth rate of PVP market demand in China will reach over 10% in the next few years, and a 1,000-ton device will be built in China, and the demand for ethanolamine will also increase.
China's ethanolamine is mainly used in surfactants, pharmaceuticals and pesticides, polyurethane, gas purification, rubber additives and other fields. The consumption ratio is roughly: 31% for surfactants, 26% for pharmaceuticals and pesticides, 12% for polyurethanes, 7% for gas purification, 5% for rubber auxiliaries, 5% for textiles, and 4 for metal cleaning and processing. %, about 10% in other areas. It is expected that the consumption structure of ethanolamine in China will not change much in the next few years.
With the rapid development of China's economy, the downstream industries of ethanolamine are growing at a relatively high rate, and domestic ethanolamine production is far from meeting the needs of downstream industries. In 2005, domestic ethanolamine production reached 30,000 tons, but the apparent consumption increased to 116,500 tons. Although the degree of import dependency declined slightly, it still reached 75%, which seriously affected the normal development of domestic ethanolamine industry. On November 14, 2004, the Ministry of Commerce issued an announcement to impose anti-dumping duties of 9% to 74% on imported ethanolamine originating in Japan, the United States, Iran, Malaysia, Taiwan, and Mexico, with a term of five years. After the introduction of ethanolamine anti-dumping measures, the rapid growth of ethanolamine imports in China has been initially contained.
It is reported that Fushun North Chemical Company plans to expand ethanolamine capacity to 50,000 tons/year in 2010. Nanjing Chemical Industry Park, Yangzhou (Instrument) Chemical Industry Park, Xinjiang Wusu, and Anhui Huaihua Fine Chemicals Company also have new ethanolamine projects. The intention is to increase the total capacity by more than 100,000 tons/year. However, due to the large dependence of the new ethanolamine project on the effective supply of ethylene oxide, it is expected that the new production capacity of ethanolamine in China will not increase substantially. In 2010, the production capacity of ethanolamine will reach 80,000 tons/year. The domestic ethanolamine demand will continue to maintain a steady growth trend. It is expected that the average annual growth rate of consumption will be 4.7% from 2006 to 2010, and the domestic demand will reach 146,000 tons in 2010. In other words, in 2010, there is still a market gap of 86,000 tons/year that needs to be relied on imports. Therefore, experts suggest that in the implementation of raw materials, China's need to build l ~ 2 sets of 40,000 tons / year ethanolamine production facilities to change the domestic market in short supply, high degree of dependence on imports.
Product demand exceeds import dependence High ethanolamine Urgently needed to build large-scale equipment
Although China's ethanolamine industry developed earlier, compared with foreign developed countries, it is still in a backward situation, that is, the production scale is small, the product quality is poor, and the import dependence is high. In the late 1990s, Fushun and Jilin successively introduced foreign technology and equipment to embark on the development of the ethanolamine industry in China. But so far, domestic ethanolamine production still can not meet the market demand, so industry experts believe that China urgently needs to build a large-scale ethanolamine production plant.
